Rolling road at Northampton Motorsport today to find out why the Cup car felt so slow. It felt like an ignition problem to me, from the way it drove.
Looks fast, doesn't it? It wasn't.
First run and a whopping 45.8 bhp at the flywheel. Turns out the distributor was completely seized.
So the distributor was dismantled, freed up and reassembled.
Second run much better with 98bhp at 6300 rpm and still climbing at that point (factory figure is 110 bhp @ 6100 rpm)
Before (bottom) and after (top) for comparison.
This next picture shows that the mixture is too lean. We didn't have time to sort that out today, so there will be a future return visit to sort out this, the exhaust leak, and probably to finish off the safety equipment etc so that it's ready to go on track. I'm confident we should be able to achieve more or less factory power output.
